New research has suggested that tranexamic acid has the potential to prevent people dying from head injuries. The CRASH-2 Intracranial Bleeding Study highlighting the potential of the cheap, off-patent drug to help people suffering from brain trauma is published online by the BMJ today. According to the collaborators – led by the London School of Hygiene & Tropical Medicine - the results provide strong grounds to test the effect of this treatment in a larger and definitive study. The forthcoming CRASH-3 trial (http://crash3.lshtm.ac.uk/) will determine reliably the effectiveness of tranexamic acid in patients with head injury.
